Although the year was a significant improvement on 2005, Honda were not to be challenging for the championship after impressive winter form. The car was quick on qualifying, but less so in the races. A performance trough mid-season also led to the team parting company with the car's designer, Geoff Willis.

However, things improved from the German GP, culminating in Button's first F1 win in Hungary. Button was generally the stronger driver throughout the season, and it was felt that he deserved to get Honda's first win in their F1 return.

Honda finished the season strongly with a run of podium finishes. They also successfully introduced their 2007-spec engine before the season was over.

The team eventually finished fourth in the Constructors' Championship, with 86 points.
